Abstract
The utility model relates to a total excursion dynamic balanced lifting-and-pulling head part of crystal growth furnace, which can realize that components are all in a dynamic balancing state when a rolling wheel is in each stroke position during the crystal pulling total excursion process, the interference to a seed crystal shaft because of the vibration due to the damages of dynamic balance does not exist any longer. Taking a rotating center of a lifting-and-pulling head as a basic, a balancing shaft is arranged on the corresponding direction of the rolling wheel of the components, the balancing shaft is linked with the rolling wheel, the linkage direction is reverse, when the components rotate, the centrifugal force caused by the quality of the rolling wheel is equal to the centrifugal force caused by the quality of a balancing shaft, the directions are reverse and counteracted, and the total excursion is in an unchanged dynamic balancing state.
Description
Technical field
The utility model relates to a kind of head member that lifts of crystal growing furnace, uses this parts, and in the time of can realizing that rolling wheel is in different positions in the crystal pulling process, parts all are in good dynamic equilibrium state.No longer occur owing to transient equilibrium destroys the disturbance to seed shaft that causes that vibration brings.
Background technology
At present the known head member that lifts because its structure is asymmetric, is all done transient equilibrium, and the rolling wheel that moves in the work can only be fixed on an agreement place when doing transient equilibrium, as fixing when the suitable seeding position.But rolling wheel need have displacement during real work, and this moment, the parts transient equilibrium destroyed.
Summary of the invention
Lift the head member rolling wheel and move and destroy this parts transient equilibrium and cause vibration and bring in order to overcome existing crystal growing furnace seed shaft turbulent deficiency, the utility model provides a kind of crystal growing furnace to have the dynamically balanced head member that lifts of total travel, in the time of can realizing that with these parts rolling wheel is in each travel position in the crystal pulling total travel process, parts all are in good dynamic equilibrium state.
The technical scheme that its technical problem that solves the utility model adopts is: to lift the head member rotation center is base, parts rolling wheel counterparty to balancing shaft is set, this balancing shaft and rolling wheel are pressed the parts rotation center and are the base interlock, the interlock direction is opposite, rolling wheel barycenter and balancing shaft barycenter are cancelled out each other to the variation of rotation center, realize that total travel all is in constant dynamic equilibrium state.The rolling wheel axle rotates by key connecting with the rolling wheel that the sheet gear is housed, and axially moves by the rolling wheel following nut simultaneously.And by lamellar tooth wheel shaft gear shape balancing shaft, shaft gear shape balancing shaft is done the direction opposite with rolling wheel by the balancing shaft following nut and is moved.Therefore, it is constant to lift the whole centroid position of head member, and the transient equilibrium of these parts does not destroy yet.
The beneficial effects of the utility model are that in the time of can realizing that rolling wheel is in each travel position in the crystal pulling total travel process, parts all are in good dynamic equilibrium state.No longer occur owing to transient equilibrium destroys the disturbance to seed shaft that causes that vibration brings.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is the direction of overlooking that lifts head member of the present utility model, and the rolling wheel wireline extends downwards along the parts rotation center.
1. motors among the figure, 2. balancing shaft, 3. balancing shaft following nut, 4. rolling wheel, 5. rolling wheel axle, 6. rolling wheel following nut, 7. sheet gear, 8. parts chassis, 9. rolling wheel centroid position, 10. balancing shaft centroid position, 11. parts rotation centers.
A is the distance of rolling wheel axis and rotation center, and B is the distance of balancing shaft axis and rotation center.
M
1Be rolling wheel quality, M
2Be the balancing shaft quality.
Embodiment
In the accompanying drawing, motor 1 rotates rolling wheel axle 5, and rolling wheel axle 5 rotates by key connecting with the rolling wheel 4 that sheet gear 7 is housed, and axially moves by rolling wheel following nut 6.Rotate the balancing shaft 2 with shaft gear by sheet gear 7 simultaneously, balancing shaft 2 is done the direction opposite with rolling wheel 4 by balancing shaft following nut 3 and is moved.When parts rotate, the rolling wheel mass M
1The centrifugal force and the balancing shaft mass M that form
2The centrifugal force equal and opposite in direction that causes, direction is offset mutually on the contrary, and when rolling wheel 4 was in different travel position with balancing shaft 2, parts all were in constant dynamic equilibrium state.
When size A=B, M
1=M
2
When size A ≠ B, M
1* A=M
2* B.
